SYSTEM DESCRIPTION

When a 7500 series facepiece is combined with a pair of approved 3M filters
(see Reference Leaflet) it forms a filtering apparatus for respiratory protection.
Such apparatus is designed to remove potentially harmful gases, vapours and/or
particulates from the surrounding atmosphere.
The 7500 series facepiece may also be used with the 3M air supply units as specified in
the Reference Leaflet.
APPROVALS
These respirators have been produced to comply with the requirements of the Australian
Standard AS/NZS 1716:2003 under an agreed production certification scheme operated
during manufacture in accordance with the SAI Global StandardsMark programme.
LIMITATIONS TO USE
Use this respirator strictly in accordance with all instructions:
• contained in this booklet
• accompanying other components of the system (e.g. 3M 7500 series facepiece reference
leaflet, filter / air supply unit user instructions).
Do not use in concentrations above those specified in Technical Specifications.
Do not use for respiratory protection against unknown atmospheric contaminants or
when concentrations of contaminants are unknown or immediately dangerous to life or
health (IDLH) or in atmospheres containing less than 19.5% oxygen (3M definition.
Individual countries may apply their own limits on oxygen deficiency. Please seek advice
if in doubt).
Only use with the filters/air supply units and spares/accessories listed in the Reference
Leaflet and within the usage conditions given in the Technical Specification.
Only for use by trained, competent personnel.

e) You taste or smell contaminants or an irritation occurs.
Never modify or alter this product, replace parts only with original 3M parts.
Do not use in oxygen or oxygen-enriched atmospheres.
Do not use in flammable or explosive atmospheres (Call 3M OH & ES Technical
Services at your local 3M office).
If using with a 3M air supply unit:
• At very high work rates, the pressure in the facepiece may become negative at peak
inhalation flow.
Adjust equipment as appropriate or consider an alternative form of respiratory
protective device.
If using in supplied air mode, ensure that:
• The source of the air supply is known.
• The purity of the air supply is known.
• The air supply is of a breathable quality, to AS/NZS 1715.
Only suitable for use by clean-shaven personnel, facial hair under the seal reduces
protection.
These products contain no components made from natural rubber latex.
National regulations may impose specific limitations on the use of filters depending on
the filter class and the facepiece used.
Use of any 3M facepiece/filter combination should be in accordance with applicable
safety & health standards, respiratory selection tables, AS/NZS 1715 or in accordance
with the recommendations of an occupational hygienist.

PREPARATION FOR USE

Inspection
Check apparatus is complete, undamaged and correctly assembled, any damaged or
defective parts must be replaced before use.
The following inspection procedure is suggested:
1. Check the facepiece for cracks, tears and dirt. Be certain the facepiece, especially the
face seal area, is not distorted. The material must be pliable – not stiff.
2. Examine the inhalation valves for cracking or tearing. Lift valves and inspect valve
seat for dirt or cracking.
3. Ensure that the head straps are intact and have good elasticity.
4. Examine all plastic parts for signs of cracking or fatigue.
5. Make sure all gaskets are properly seated.
6. Remove the exhalation valve cover and examine the exhalation valve and valve seat
for signs of dirt, distortion, cracking or tearing.
Replace the exhalation valve cover.
Undertake pre-use checks on filters/air supply unit as outlined in the appropriate user
instruction.
